Dead RV outlets are usually GFCI trip, branch breaker, inverter transfer, or loose stab connection—not random outlet failure across the coach.
One dead outlet — local GFCI, loose wire, backstab.
Whole side dead — upstream GFCI or breaker.
Works on gen not shore — pedestal, EMS, adapter.
Safety: Verify power is off before removing cover plates. Use a non-contact tester after breaker off.
Quick decision tree
Reset every GFCI you can find (bath, kitchen, exterior).
Power returns. Something downstream leaked current—unplug devices and retest.
No change. Go to B.
Check the RV main panel breakers—including inverter pass-through if equipped.
Tripped. Reset once; if immediate re-trip, remove loads and hunt short.
OK. Go to C.
Measure voltage at a working vs dead outlet.
No voltage at first outlet of chain. Wiring fault—pro.
How RV 120V branches are protected
GFCI devices protect people from ground faults; they cascade so one reset restores many outlets. AFCI may protect bedroom circuits in newer builds. Inverter systems insert another transfer layer—outlets may be on inverter subpanel rules.

Top causes
Tripped GFCI — coffee maker, space heater on wet counter.
Main or branch breaker — overload on 30A service.
Bad shore adapter — overheated dogbone.
Inverter offline or fault — no pass-through.
Loose neutral — dangerous—pro.

Replace vs repair
Repair loose screws on side-wired devices; avoid backstab on heavy loads. Replace outlets that are warm, discolored, or loose in the box.
Work dead to hot relative to ground—never assume neutral is safe if neutral faults exist.
Field insight: Exterior GFCI in a wet bay often feeds kitchen galley outlets—always reset the outside plate when half the coach is dead after washing the rig.
